Can you make spontaneous hard cider from pasturized pressed apple juice? I got some Solana Gold Organics apple juice, it is dark, cloudy juice, not the clear stuff from the store, and of course it has to be pasturized to be sold

It tastes like apple cider, I thought it would make some good hard cider, so I set some in a jar on my counter loosely covered with a thin piece of fabric, and it is now moldy and smells bad. Why did it not ferment? I did it exactly how Wild Fermentation says to do it, and it does not specify that you can use pasturized juice, so I thought it didnt matter. its the only reason I can think of that it didnt work :/ Any ideas?

I don't think you can make it without yeast. We make cider from the Whole Foods brand cider (365). I just pour a little off the top, add some ale yeast (I hate champagne yeast) and out either a balloon or an airlock on the top of the jug.

Hmm I didnt know you could add yeast lol, the Wild Fermentation has 2 recipes for hard cider and both just say to let it sit out, add nothing, do nothing, and it will ferment. Maybe if I put it outside, the yeast would find it first rather than the mold? Lol, idk
